ANTISKIDDING DEVICE FOR VEHICLE=WHEELS;

SPECIFICATION forming part of Letters Patent No. 740,184, dated September 29, 1903. Application filed June 13 1903 Serial No. 161,401. (No model.)

T0 @255 whom it may concern: I

Be it known that I, WILLIAM DRAPER SAINSBURY, a subject of the King of the United Kingdom of Great Britain, residing at 27 Westmorelandstreet, Dublin, Ireland, have invented a certain new and useful Device for Preventing Skid of Vehicle-Wheels, of which the following is a specification.

This invention relates to a device for pre venting skid of vehicle-wheels, such as those of motor-cars; and it has more especially for its object to provide a construction comprising treadwardprojecting horns attached to the rim of the Wheel and which in normal running of the car are adapted to rise and fall with the tire without injury to the latter, but which when the tire skids, side slips, or rolls will come in rigid contact with the ground, dragging sidewise thereon to prevent such skidding or side slip.

A further object of the invention is to provide a construction which can be readily detached from the Wheel altogether and in which also without completely detaching the device the projecting horns can be raised out of contact with theground when desired.

In the accompanying drawings, which illustrate the invention, Figure 1 is a vertical section of the improved device, showing a wheel rim and tire, also in section. Fig. 2 is a side elevation of a motor-car wheel fitted with three of such devices.

As shown inthe drawings, the device, a number of which are preferably mounted on the wheel-rim at'equal intervals, comprises a U-shaped bridge a, of metal or other rigid material, embracing the rim 1? of the Wheel and the divergent horns of which project to ward the tread on either side of the rim and clear of the tire b and may assume any convenient form, such as shown. This U -shaped body is adj ustably mounted on the wheelrim 5; but when it 'is intended to provide against skidding of the wheel it is set in a position such as shown in Fig. 1, the horns extending to or somewhat beyond the tread of the tire b. V

To serve as a liner between the tire b and the horns a, which contacting with the ground rise and fall with the tire I) on account of their resilient connection with the rim, is interposed a plate (1, of brass or other metal or suitable material of U or other suitable shape, which is mounted stationarily relative to the rim and which receives the friction of the moving horns which would otherwise wear out the tire. To this liner d is rigidly connected a tubular shank e, screw-threaded externally, as shown, and which passes through the arch of the U-shaped body, which moves up and down relatively to said shank.

Fixed to the rim 1) is a metal or like plate f, through an orifice in which plate f and liner d passes the stem of a tubular socket g, the said socket g being prevented from completely passing through said plate f by a flange g. Passing through the tubular shank e is a screw-pin h, the nose of which engages internal screw-threads in the socket g and whose head h abuts against the free extremity of the shank 2, so as to provide a more or less rigid connection between the shank e and the rim. b of the wheel. Surrounding the lower part of the shank e is a sleeve is, screw threaded internally to engage said shank and whose stem passes freely through the central orifice in the plate, which plate rests against the flange 7c of the sleeve 7c or against an interposed washer Z. Engaging the sleeve 71; above the U-shaped body a is a wing-nut m,'r0tati0n of 'w hich,'and consequent rotation of the sleeve k,traverses the latter along the shank eand at the same timevmoves the U-shaped body a up or down relatively to the shank. Fixed to the free end of the shank against the head of the screw-pin h is a washer a, through which passes a split pin a to prevent the said screw-pin h from turning, and surrounding the shank 6 between the washer 'n and the wing nut m is a helical spring 0 under compression, the effect of which is to provide a resilient connection between the horns a and the rim I) of the wheel, for when the extremities of the said horns are pressed on the ground the'horns are forced upward, the arch traveling along the sleeve is and moving the wing-nut m to further compress the spring 0, which when the pressure is relieved depresses the horns to abut against the washer Z.

' The tension of the spring may be varied by rotating the wing-nut m, and therewith the sleeve 70, so as to vary the distance between the latter and the washer n and lower the prongs to compensate for wear.

When not required, the device can be detached by unscrewing the screw-pin h, in which case a cap is supplied to close the socket g, or by screwing up the wing-nut m the horns a can be raised clear of the ground, so that the tire alone makes contact therewith.

It will be understood that in rotation of the wheel, in which a plurality of such devices may be provided, the horns a will roll over the ground during normal forward travel of the vehicle and owing to their resilient connection with the rim b will rise and fall with the tire b Without giving rise to undue resistance; but if the tire skids, slips, or rolls the horns a will not yield, but will drag sidewise on the ground and prevent such skidding.
